Although the promised keyboard add-on never appeared (this was one of Mattel's original selling points - the fact the console would also act as a computer - something that never actually passed the test phases) a voice synthesis add-on was released in 1982, known as the Intellivoice. This was a 'plug-through' adapter, that added speech to games which supported this feature. These included B17-Bomber, where you would hear orders passed to you from your co-pilots!

The Intellivision soon had new competition from the Colecovision, which had better Graphics & Sound, support from arcade companies like Nintendo, Sega & Konami, and even had an add on adapter that allowed it to play all the Atari games currently on the market. As a result, the Intellivision lost some of its market share to the new console.

In an attempt recoup some of their losses from Atari & Coleco, Mattel introduced the Intellivision II in 1983, which was a cheaper looking black plastic unit, retailing at $150 (I'm sure this is just a coincidence, but Atari moved away from their 'wood grain' console, to the sleeker black-plastic 2600 around a similar time!). And, just like Coleco had done the previous year, they also introduced the System Changer Module, which allowed Atari 2600 games to be played on the Intellivision.

Unfortunately for Mattel (and indeed Atari, Coleco & MB) the influx of new consoles and cheap video games causes saturation of the market - there simply weren't enough sales to go round. All four main console manufacturers slashed the prices of their consoles, resulting in massive losses, redundancies and eventually the crash of the American Video Game Market. Enter stage right a Moustached Italian Plumber and a Japanese Pachinko machine manufacturer, and a whole new era of video gaming is born.

So that's the potted history of the Colecovision. A console which lost out to the video game crash due to poor management decisions and market saturation. A shame really, with over 100 titles, the console was starting to have a nice catalogue, thanks to the 'Blue Sky Rangers', Mattel's in-house software development team. However, titles such as Space Armada, Star Strike & Mission X still get some play time around my house - the Intellivision is still the console of choice for my missus. And with the recent release of Intellivision Lives for the X-Box & Playstation 2, a whole new generation are being introduced to these games too.
